Aerokote fuel proofer, how many coats?

I'm using Aerokote fuel proofer for the first time, after my rather unsuccesful experience with Spectra. I'm applying it over Solartex and Oracover, principally to make the Solartex easier to wipe down and to seal all the seams. The instructions say to sand between coats. My question is, how many coats are required? Also, is the sanding necessary and if so, what grade paper should I use?

Hello Martin . Aerokote will adhere to solartex fine but not to oracover unless you have abraded it with a scotch pad first. One coat should do the job and seal the joints fine . If a second coat is really needed then rub down lightly with 500 Wet and dry used wet .Be careful of adding weight as sprayed paint will build weight very quickly especially on the tail end. personally I would only use one coat as it covers welln and only apply a second coat if the first has any defects, runs dust etc . It isn't a high build paint so wont fill the weave on the solartex but the gloss should help with the cleaning.

Martin is the Solartex over a solid or open structure? In the dim recesses of my mind I seem to recall that Aerokote isn't very flexible & over time will crack & craze if applied to a flexible surface..... it might be worth doing a test piece first..... Can anyone else remember if I'm right about this?? I might very well be wrong....

Clearcoat is available & is made by Solarfilm to do exactly what you want to do.....might be worth a look....

It's over a solid structure, so hopefully should be OK.

I've used clearcoat on the engine bay and fuel tank bay over the bare wood, but hadn't thought to use it on the rest of the model, mainly due to the high solvent content which my dearly beloved can't stand the smell of.
